Abstract

A method of cleaning a hard floor surface with a surface maintenance vehicle including the steps of generating a foam-like aerated cleaning liquid, selectively conveying the foam-like aerated cleaning liquid to the hard floor surface and a scrubbing medium (22) operatively coupled to the surface maintenance vehicle, scrubbing the hard floor surface with said rotation scrubbing medium (22) and said foam-like aerated cleaning liquid so as to loosen soil from the hard floor surface leaving behind a soiled solution of cleaning liquid and soil, and removing at least a portion of the soiled solution from the hard floor surface through a fluid recovery device (32). Additional aspects of the present invention include devices for performing the cleaning method.

Claims

AMENDED CLAIMS[received by the International Bureau on 31 January 2003 (31.01.03) claims 1, 3-6 amended, claims 14-39, 41 deleted, claim 40 amended and renumbered claim14, claims 42-52 amended and renumbered claims 15-25, claim 53 renumbered claim 26, claims 54-57 amended and renumbered claims 27-30];
1. A method of cleaning a hard floor surface with a surface maintenance vehicle, said method comprising the steps of: generating a foamed cleaning liquid comprising water and a surfactant; wetting the hard floor surface with the foamed cleaning liquid; scrubbing the hard floor surface with a rotating scrubbing medium and said foamed cleaning liquid so as to loosen soil from the hard floor surface leaving behind a soiled solution of cleaning liquid and soil; and removing at least a portion of the soiled solution from the hard floor surface through a fluid recovery device.
2. A method of claim 1 wherein the scrubbing medium is a disk-type scrub brush rotating about a generally vertical axis of rotation relative to said hard floor surface.
3. The method of claim 1 wherein the scrubbing medium is a cylindrical-type scrub brush rotating about a generally horizontal axis of rotation and generally transverse to an operating direction of movement of said surface maintenance vehicle.
4. The method of claim 1 wherein the step of generating the foamed cleaning liquid is selectively achieved by way of an air compression process, an agitation process, or both.
5. The method of claim 1 wherein the step of generating the foamed cleaning liquid is achieved by way of a process utilizing compressed air and pressurized cleaning liquid.
6. The method of claim 1 wherein the step of removing soiled solution from the hard floor surface is achieved via a non-vacuum process.
7. The method of claim 6 wherein the non-vacuum process includes the steps of: physically wiping the hard floor surface with a wiping medium; lrfxing soiled solution away from the hard floor surface; and depositing e soiled solution in a recovery tank.
23
8. The method of claim 1 wherein the step of selectively conveying the foamed cleaning liquid to the hard floor surface and the scrub brush includes the step of selectively applying the foamed cleaning liquid directly to the floor surface and directly to the scrubbing medium.
9. The method of claim 1 wherein the cleaning liquid is selected such that the foamed cleatiing liquid substantially de-aerates on the hard floor surface prior to removal of the soiled solution.
10. The method of claim 1 wherein the cleaning liquid is provided through a step of mixing the water with the surfactant within a solution tank.
11. The method of claim 1 wherein the cleaning liquid is provided through a step of mixing the water with the surfactant dispensed from a chemical dispenser.
12. The method of claim 11 wherein the chemical dispenser includes a removable cartridge element containing said surfactant

15. The device of claim 14 wherein the aerator includes a mixing element receiving pressurized cleaning
Hquid, pressurized air, or both.
16. The device of claim 14 wherei the scrub medium is a disk-type scrub brush rotating about a generally vertical axis of rotation relative to the hard floor surface.
17. The device of claim 14 whereinthe scrub medium is a cylindrical-type scrub brush rotated about a generally horizontal axis of rotation relative to the hard floor surface.
18. The device of claim 14 wherein the cleaning liquid is selected such that the foam-like aerated cleaning liquid substantially de-aerates on the hard floor surface prior to removal of the soiled solution.
19. The device of claim 14 wherem the fluid recovery device is a vacuum device for conveying soiled solution from the hard floor surface.
20. The device of claim 14 wherein the surfactant is delivered from a chemical dispenser.
21. The device of claim 20 wherein the chemical dispenser includes a removable chemical cartridge.
22. The device of claim 14 wherein the fluid conveyer directs the aerated cleaning liquid through a conduit having a discharge outlet proximate to the center of the disk scrub brush.
23. The device of claim 14 further comprising: a defoaming device for de-aerating foam recovered by the device.
24. The device of claim 23 wherein the defoaming device includes a device for dispensing a chemical defoamer.
25. The device of claim 23 wherein the defoaming device is a radiant heating element provided in operative relation to recovered foam.
26. A surface maintenance vehicle for a hard floor surface cleaning process comprising:
25 a tank holding water; a chemical dispenser, said dispenser delivering a chemical into water to form a cleaning liquid; an aerator generating an aerated cleaning liquid from the cleaning liquid; a fluid conveyor in fluid communication with the aerator, said fluid conveyor directing the aerated cleaning Hquid into contact with the hard floor surface; a scrub brush engaging the hard floor surface and the aerated cleaning liquid to loosen soil from the hard floor surface to leave behind a soiled solution of cleaning liquid and soil; and a fluid recovery device removing at least a portion of the soiled solution from the hard floor surface.
27. The surface maintenance vehicle of claim 26 wherein the chemical dispenser includes a removable cartridge containing a surfactant.
28. The surface maintenance vehicle of claim 26 wherein the chemical dispenser dispenses the chemical into the tank.
29. The surface maintenance vehicle of claim 26 wherein the chemical dispenser dispenses the chemical into a conduit for mixing water wiftiin the conduit with the chemical.
30. The surface maintenance vehicle of claim 26 further comprising a de-foaming device for reducing the volume of recovered foam within a recovered solution tank, said defoaming device selected from a group including: a device for dispensing a chemical defoamant and a radiant heating element
